Iranian President Mahmoud Ahmadinejad arrived in Beirut on Oct. 13 for his first official visit to Lebanon since becoming president in 2005. He is reportedly returning to the country after a stint there in the 1980s as a young Islamic Revolutionary Guard Corps (IRGC) officer tasked with training Hezbollah in Lebanon’s Bekaa Valley. A great deal of controversy is surrounding his return. Rumors are spreading of Sunni militants attempting to mar the visit by provoking Iran’s allies in Hezbollah into a fight (already the car of a pro-Hezbollah imam who has been defending Ahmadinejad has been blown up), while elaborate security preparations are being made for Ahmadinejad to visit Lebanon’s heavily militarized border with Israel.

Rather than getting caught up in the drama surrounding the Iranian president’s visit, we want to take the opportunity provided by all the media coverage to probe into a deeper topic, one that has been occupying the minds of Iranian, Syrian and Hezbollah officials for some time. This topic is the durability of the Iran-Hezbollah-Syria alliance, which STRATFOR believes has been under great stress in recent months. More precisely, the question is: What are Syria’s current intentions toward Hezbollah?

The Origins of the Alliance

To address this topic, we need to review the origins of the trilateral pact, starting with the formation of an alliance in 1979 between secular Alawite-Baathist Syria and the Islamic Republic of Iran. Ideologically speaking, the Syrian Alawite elite represent an offshoot of Shiite Islam that the Sunnis consider apostate. They found some commonality with the Shiite clerical elite in Tehran, but there were also broader strategic motivations in play. At the time, Syria was on a quest to establish the country’s regional prowess, and it knew that the first steps toward this end had to be taken in Lebanon. From the Syrian point of view, Lebanon is not just a natural extension of Syria; it is the heartland of the Greater Syria province that existed during Ottoman times. Since the days of Phoenicia, what is modern-day Lebanon has been a vibrant trading hub, connecting routes from the east and south to the Mediterranean basin. For Syria to feel like it has any real worth in the region, it must dominate Lebanon.

A civil war that had broken out in Lebanon in 1975 (and lasted through 1990) afforded Syria such an opportunity. The main obstruction to Syria’s agenda at the time, besides Israel, was the Palestine Liberation Organization (PLO) under Yasser Arafat, whose vision for a unified Palestine and whose operations in Lebanon ran counter to Syria’s bid for regional hegemony. The PLO, in fact, was one of the main reasons Syria intervened militarily in Lebanon in 1975 on behalf of its Maronite Christian allies. At the same time, Syria was looking for an ally to undermine the Baathist regime of Saddam Hussein in Iraq, with whom the Syrian Baathists had a deep-seated rivalry. An alliance with Iran would grant Syria some much-needed individuality in a region dominated by the Arab powers Saudi Arabia and Egypt.

Coming off the success of the 1979 Islamic Revolution in Iran and going into what would become a long and bloody war with Iraq, Iran was also looking for a venue to counter the Baathist regime in Baghdad. In addition, Iran was looking to undermine the Pan-Arab vision, establish a presence in the Levant and promote its own Islamic vision of government. In opposition to Israel, Hussein and Arafat, Iran and Syria thus uncovered the roots of an alliance, albeit one that was shifting uneasily between Syrian secularity and Iranian religiosity.

The adoption of Hezbollah by the two unlikely allies in 1982 was what helped bridge that gap. Hezbollah, an offshoot of Amal, the main Shiite political movement at the time, served multiple purposes for Damascus and Tehran. Syria found in Hezbollah a useful militant proxy to contain obstructions to Syrian influence in Lebanon and to compensate for its own military weakness in comparison to Israel. In the broader Syrian strategic vision, Hezbollah would develop into a bargaining chip for a future settlement with Israel once Syria could ensure that Lebanon was firmly within Syria’s grasp and was therefore unable to entertain a peace deal with Israel on its own.

The Iranians saw in Hezbollah the potential to export its Islamic Revolution into the Arab world, a strong binder for its still new and shaky alliance with Syria and a useful deterrent in dealing with adversaries like Israel, the United States and Saudi Arabia. So, Iran and Syria set out to divide their responsibilities in managing this militant proxy. Iran was primarily in charge of bankrolling, training and enforcing the group’s ideological loyalty to Tehran with IRGC assistance. Syria was in charge of creating the conditions for Iran to nurture Hezbollah, mainly by permitting IRGC officers to set up training camps in the Bekaa Valley and by securing a line of supply for weapons to reach the group via Syria.

But the triumvirate did not get off to a very smooth start. In fact, Hezbollah and Syria clashed a number of times in the early 1980s, when Syria felt the group, under Iranian direction, went too far in provoking external intervention (and thus risked drawing Syria into conflict). If Hezbollah was to operate on Syrian territory (as Syria viewed it) in Lebanon, Syria wanted Hezbollah operating on its terms. It was not until 1987, when Syrian troops in Lebanon shot 23 Hezbollah members, that Hezbollah fully realized the importance of maintaining an entente with Syria. In the meantime, Hezbollah, caught between occasionally conflicting Syrian and Iranian agendas, saw that the path to the group’s survival lay in becoming a more autonomous political — as opposed to purely militant — actor in the Lebanese political arena.

A Syrian Setback

The Iran-Hezbollah-Syria alliance operated relatively smoothly through the 1990s as Hezbollah gradually built up its political arm and as Syria kept close watch on the group through its roughly 14,000 troops and thousands of intelligence agents who had remained in Lebanon since the end of the civil war. In 2000, with Iranian and Syrian help, Hezbollah succeeded in forcing Israel to withdraw from Lebanon’s southern Security Zone, an event that greatly boosted Hezbollah’s credentials as a Lebanese nationalist actor.

But fresh challenges to the pact came with the turn of the century. The 2003 U.S. invasion of Iraq, in particular, was a defining moment for both Iran and Syria. The two allies felt enormously uncomfortable with having the world’s most powerful military on their borders, but they were also presented with an immediate opportunity to unseat their mutual archrival, Saddam Hussein. Iran and Syria also had different endgames in mind for a post-Hussein Iraq. Iran used its political, militant and intelligence links to consolidate influence in Iraq through the country’s Shiite majority. In contrast, Syria provided refuge to Iraq’s Sunni Baathists with the aim of extending its sphere of influence in the region through a secularist former-Baathist presence in Baghdad. The Syrians also planned to use those Sunni links later to bargain with the United States for a seat at the negotiating table, thereby affirming Syrian influence in the region.

But before Syria could gain much traction in its plans for Iraq, its agenda in Lebanon suffered a serious setback. On Feb. 14, 2005, a massive car bomb in Beirut killed former Lebanese Prime Minister Rafik al-Hariri, a powerful and vocal opponent of Syrian authority in Lebanon. The bombing is strongly believed to have been orchestrated by elements within the Syrian regime and executed by members of Hezbollah. While a major opponent of the Syrian regime was thereby eliminated, Syria did not anticipate that the death of al-Hariri would spark a revolution in Lebanon (which attracted the support of countries like France and the United States) and end up driving Syrian troops out of Lebanon. The vacuum that Syria left in Lebanon was rapidly filled by Iran (via Hezbollah), which had a pressing need to fortify Hezbollah as a proxy force as war tensions steadily built up in the region over Iran’s nuclear ambitions. Though Syria knew it would only be a matter of time before it would return to Lebanon, it also had a strategic interest in demonstrating to the Israelis and the Americans the costs of Syria’s absence from Lebanon. The regime wanted to show that without a firm Syrian check on Hezbollah, disastrous events like the 2006 summer confrontation between Hezbollah and Israel could occur.

The Syrian Comeback

It has now been more than five and a half years since the al-Hariri assassination, and there is little question that Syria, once again, has reclaimed its hegemonic position in Lebanon. The Syrian intelligence apparatus pervades the country, and Lebanese politicians who dared to speak out against the Syrian regime are now asking for forgiveness. In perhaps the most glaring demonstration of the political tide shifting back toward Damascus, Saad al-Hariri, the son of the slain al-Hariri and Lebanon’s reluctant prime minister, announced in early June that Lebanon had “made a mistake” in making a “political accusation” against Syria for his father’s murder. The message was clear: Syria was back.

That message did not necessarily sit well with Hezbollah and Iran. Syria wants to keep Hezbollah in check, returning to the 1990s model when Syrian military and intelligence could still tightly control the group’s movements and supplies. Iran and Hezbollah have also watched as Syria has used its comeback in Lebanon to diversify its foreign policy portfolio over the past year. Saudi Arabia and Turkey, for example, have been cozying up to Damascus and have quietly bargained with the al Assad regime to place checks on Hezbollah as a way to undermine Iran’s key proxy in the Levant. As long as these regional powers recognize Syria’s authority in Lebanon, Syria is willing to use those relationships to exonerate itself from the al-Hariri assassination tribunal, rake much-needed investment into the Syrian economy and, most important, re-establish itself as a regional power. Syrian President Bashar al Assad’s decision to visit Beirut alongside Saudi King Abdullah was a deliberate signal to Hezbollah and Iran that Syria had options and was not afraid to display them.

This does not mean Syria is ready and willing to sell out its Hezbollah and Iranian allies. On the contrary, Syria derives leverage from maintaining these relationships and acting as the bridge between the Shiite revivalists and the Sunni powers. Syria has illustrated as much in its current mediation efforts among the various Iraqi factions that are torn between Iran on one side and the United States, Saudi Arabia and Turkey on the other. But if we go back to reviewing the core reasons Syria agreed to an alliance with Iran and Hezbollah in the first place, it is easy to see why Hezbollah and Iran still have a lot of reason to be worried.

Syria’s priority in the early 1980s was to achieve suzerainty in Lebanon (done), eliminate the threat posed by Saddam Hussein in Iraq (done) and remove any key obstacles in Lebanon that could challenge Syria’s authority. In the 1970s, that obstacle was the PLO. Today, that obstacle is Hezbollah and its Iranian backers, who are competing for influence in Lebanon and no longer have a good read on Syrian intentions. Hezbollah relies heavily on Syria for its logistical support and knows that its communication systems, for example, are vulnerable to Syrian intelligence. Hezbollah has also grown nervous at the signs of Syria steadily ramping up support for competing militant groups — including the Amal Movement, the Syrian Social Nationalist Party, al-Ahbash, the Nasserites, the Baath Party and the Mirada of Suleiman Franjiyye — to counter Hezbollah’s prowess.

Meanwhile, Iran is seeing one of the key prongs in its deterrent strategy — Hezbollah — grow increasingly vulnerable at a time when Iran is pressed to demonstrate to the United States and Israel that the costs of an attack on its nuclear installation are not worth incurring. The Iranian competition with Syria does not end in Lebanon, either. In Iraq, Syria is far more interested in establishing a secularist government with a former Baathist presence than it is in seeing Baghdad develop into a Shiite satellite for the Iranians.

For now, Syria is adroitly playing both sides of the geopolitical divide in the region, taking care to blend its reassurances toward the alliance and its primary negotiating partners in Saudi Arabia with threats of the destabilization that could erupt should Syria’s demands go ignored. Syria, for example, has made clear that in return for recognition of its authority in Lebanon it will prevent Hezbollah from laying siege on Beirut, whether they are ordered to do so by Tehran as part of an Iranian negotiating ploy with the Americans or whether they act on their own in retaliation against the al-Hariri tribunal proceedings. At the same time, Syrian officials will shuttle regularly between Lebanon and Iran to reaffirm their standing in the triumvirate. Behind this thick veneer of unity, however, a great deal of apprehension and distrust is building among the allies.

The core fear residing in Hezbollah and Iran has to do with Syrian intentions moving forward. In particular, Hezbollah would like to know if, in Syria’s eyes, the group is rapidly devolving from strategic patron to bargaining chip with every ounce of confidence that Syria gains in Lebanon. The answer to that question, however, lies not in Syria but in Israel and the United States. Israeli, U.S. and Saudi policymakers have grown weary of Syria’s mercantilist negotiating style in which Syrian officials will extract as much as possible from their negotiating partners while delivering very little in return.

At the same time, Syria cannot afford to take any big steps toward militant proxies like Hezbollah unless it receives firm assurances from Israel in backchannel peace talks that continue to stagnate. But Syria is also sensing an opportunity at its door: The United States is desperate to complete its exit strategy from Iraq and, like Israel, is looking for useful levers to undermine Iranian clout in the region. One such lever is Syria, which is why the mere idea of Israel and Syria talking peace right now should give Iran and Hezbollah ample food for thought.
